Flash SK-NET FDDI Firmware
This task allows the Flash firmware on the SysKonnect SK-NET FDDI adapter to be
updated.
Format Media
This task allows the selection of diskettes, hardfiles, or optical media to be formatted.
Each selection is described below.
Hardfile Attached to SCSI Adapter (non-RAID)
Hardfile Format
Writes all of the disk. The pattern written on the disk is device-dependent, for
example, some drives may write all 0s, while some may write hexadecimal
number 5F. Bad block are not reassigned.
Hardfile Format and Certify
Performs the same function as Hardfile Format. After the format is completed,
Certify is run. This certify reassigns all bad blocks encountered.
Hardfile Erase Disk
This option can be used to overwrite (remove) all data currently stored in
user-accessible blocks of the disk. The Erase Disk option writes one or more
patterns to the disk. An additional option allows data in a selectable block to be
read and displayed on the system console.
To use the Erase Disk option, specify the number (0-3) of patterns to be
written. Select the patterns to be written. The patterns are written serially; that
is, the first pattern is written to all blocks. Then the next pattern is written to all
blocks, overlaying the previous pattern. A random pattern is written by selecting
the Write random pattern? option.
Note: The Erase Disk service aid has not been certified as meeting the
Department of Defense or any other organizations security guidelines.
Use the following steps to overwrite the data on the drive:
1. Use the Erase Disk selection to overwrite the data on the drive.
2. Do a format without certify.
3. Run a second pass of the Erase Disk selection.
